Ultracold atoms that always move in the same pattern, in the form of a material called a time crystal, could potentially be used to build quantum computers with fewer errors.
In conventional computers, printed circuit boards are made of solid materials such as plastic. Boards made from time crystals contain thousands of atoms whose temperatures are nearly the same as absolute zero, one of the conditions necessary for quantum phenomena to unfold. Christophe Sacha Researchers at the Jagiellonian University in Poland have developed a mathematical blueprint for such a “temporary printed circuit board.”
